SPECIFICATION forming part of Letters Patent No. 710,908, dated October 7, 1902. Appimnon flied october 23,1901. stanno. 79,722. (Nomina To al wwnt t mld/U concern,.-

Be it known that I, SAMUEL V. VEEKS, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and useful Disk Plow, of which the following is a specification.

This invention relates to disk plows of the combined riding and walking type.

:o The object of the invention is by the employment of adjustable and positively-operating mechanism to dispense with the employment of weights for imparting the requisite pressure on the furrow-opening disk,

therebyrenderingthe plow easierof operation and lessening the number of animals required to draw the same.

A further object is generally to simplify the construction, reduce the number of parts,

2o and increase the efficiency of the plow.

'With these and other objects in view, as will appear as the nature of the invention will be better understood, the same consists in the novel construction and combination of parts z5 of a disk plow, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference' indicate corresponding 3o parts, there'is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion,

and exact manner of assemblage without departing from the scope of the invention, and

in these drawings- Figure 1 is a view in side .elevation of a disk plow embodying this invention. Fig. 2 is a View in plan of the plow shown in Fig. 1. Fig. 3 is a view in plan, showing the disk plow of Fig. 1 converted into a double-disk plow. Fig. a is a sectional detail view showing the manner in which the permanent disk is associated with its standard. Fig. 5 is a view in front elevation of the disk-holding plate. Fig. G is a fragmentary detail view of a portion of one of the disks.

Referring to the drawings, 1 designates the 5o main frame-beam, the same having straight terminals 2 and 3 and an intermediate out- .may be desired.

ward bowed or bent portion 4, the latter being provided to permit operation ofthe permanen t disk 5 without interfering with the said beam. The frame-beam has associated with it a landside wheel G, a front furrow-wheel 7, and a rearfurrow-wheel S, each of these wheels having a iianged or knife-edged tire or rim 9, as clearly shown in Fig. 2. The land-side wheel is vertically disposed, and the two furrow- 6o wheels are inclined, as usual and as shown in the above-named figure. The shaft 10 of the land-side wheel is a crank and has one terminal bend formed to constitute an axle for the wheel, which latter is held thereon in the usual or any preferred manner, and the other terminal bend mounted in and projecting beyond a sleeve 1l, carried by the lower end of the bracket 12, the upper end of which is bolted or otherwise secured to the terminal 7o 3 ofthe frame-beam. Secured to or formed integral with the sleeve 11 is a semicircular rack-plate 13, the teeth of which are engaged by a latch carried by a lever 14, rigidly secured to the outerend of the crank-shaft terminal 15, as shown in Fig. 2, by which arrangement the shaft 10 may be rocked to lift or depress the land-side wheel as required and through the medium of the latch and rackplate be firmly held in its adj usted position. 8o

The front furrow-wheel 7 is mounted upon the crank-terminal 16 of a shaft 17, the upper portion of which is slidably secured in a sleeve or casting 18, having at one side oriticed ears 19, which are engaged by an upstanding pin or stud 2O on an arm 21, the latter being firmly bolted to the terminal 3 of the frame-beam. The connection between the ears and the stud presents a joint or pivot upon which the casting 18 will turn, thus to 9o permit swinging of the furrow-wheel 7 to effect guiding of the plow to the right or left, as The means for shifting the position of the furrow-wheel 7 consists of a clevis 22, pivoted to the outer end of a hitchbar 23, the clevis being provided with plurality of openings to be engaged by the hook of the doubletree, by which means the depth of the cut of the disk 5 may be regulated through the medium of interposed mechan- Io) ism, presently to be described, the pressure on the disk being progressively increased as -arm 28, projecting from the sleeve or casting 18. Through the medium of the rod 26 it will be seen that as side draft in either direction is transmitted to the clevisthe front furrow-wheel is correspondingly turned, thereby effecting guiding of the plow. The shaft 17, as shown in Fig. 2, is rectangular in crosssection, this arrangement being provided to prevent the shaft turning independently ofthe casting and also permit vertical adjustment of the shaft, and with it the front furrow-wheel, When desired. To effect vertical adjustment of the shaft 17, a hand-lever 29 is provided, which is pivoted at its forward end to the outer side of the arm 28 and carries any preferred form of latch mechanism to en gage with the teeth of a segmental rack-plate 30, rigid with the arm 28. Connecting with the hand-lever 29 intermediate of its ends is a link 31, having its lower end secured to the shaft 17 by bolt or rivet 32, the upper end portion of the link being provided with a plurality of openings 33, one of which is engaged by a bolt 34 to secure the same to the said lever. It will be seen by this arrangement of mechanism that when the hand-lever is swung upward or downward the furrow-wheel 7 will be correspondingly elevated or depressed, whereby to permit the disk 5 to cnt deep or shallow, as maybe preferred. The plurality of openings 33 is provided to permit adjustment of the link with relation to the lever 29, thereby to increase vor diminish the range of adjustment of the front furrow-wheel.

Secured to the frame-beam is a yoke 35, through which projects the hitch-bar 23, the yoke being provided with a transverse piu 36, against which the upper side of the said bar bears. From the yoke the hitch-bar curves upward and rearward and connects at its up` per terminal with one end of a bar 37, pivoted for rocking movement upon the seatstandard 38, the lower end of the latter being rigidly secured to the terminal 2 of the frame-bar, as clearly shown in Fig. 2. The rear end of the bar 37 curves downward and is provided with a plurality of openings 39 (shown in Fig. 1) to be engaged by one end of a link 40, the other end of which is pivotally connected with an ear 4l, projecting downward from the underside of the framebeam. The seat-standard is provided with a 'plurality of openings 42, by which to permit adjustment of the bar 37 thereon, a bolt 43 serving to hold the bar 37 and seat-post 38 operatively connected. The connection between the hitch-bar 23 and the rocking bar 37 is through the medium of a bolt 44, adapted to engage alined pairs of a plurality of openings 45 and 46, respectively in the upper ends' of the said bars, by which arrangement the requisite adjustment between all of the parts may be effected as the requirements of the case may demand.

The rear furrow-wheel 8 is journaled upon one crank-terminal of a shaft 47, the other crank-terminal of which is journaled in a sleeve or casting 48, carried by one sideof the frame-beam. This furrow-wheel is adapted only for movement from rightto left, and in order to hold it in line with the furrow when the plow is moving forward a lug 49 is provided on the lower portion of the sleeve or casting to be engaged by the bend of the shaft 47 adjacent to the casting, as shown in Fig. 1, a stop-pin passed transversely through the upper terminal of the said shaft and bearing upon the casting serving to hold the two parts assembled.

The disk 5, which is constructed and operates in the manner usual to implements of this character, has disposed centrally of its back portion a plate 51, the back of which is provided with oppositely-alined recesses or depressions 52 to be engaged by projections 53 on one end of a sleeve 54, mounted in a bearing 55, carried by the lower end of a hanger 56, the other end of the sleeve being provided with a head or flange 57 to bear against the bearing. The upper end of the hanger is rigidly assembled with the framebeam by bolts 5S, adapted to engage pairs of a plurality of openings 59 in the hanger, by which arrangement the hanger may be lowered to compensate for the Wearing away of the disk. The disk 5 is provided at its center with a cone-shaped opening 60, Figs. 4 and 6, provided with radial depressions 61 to be engaged by lugs or offsets 62, carried by the under side of the head of a screw 63, the screw passing through the sleeve and being held associated therewith by a nut 64,screwed on its outer end and bearing against the ange 57. By the manner of associating the sleeve, plate, and disk these are all rigidly connected and are caused to rotate within the bearings 55. The coaction between the radial depressions 61 and lugs 62 of the screw-head serves to hold the screw against turning when the nut 64 is being seated, thus insuring the proper close union between the parts.

In Fig. 3 there is shown a form of embodiment of the invention wherein two disks are employed, and when this is desired a supplemental hitch-bar 65 is connected with the hitch-bar 23, to which is connected a supplemental rocking bar 66, operating in the same manner as the rocking bar 37 and connected with the frame through a link corresponding to the link 40 and operating in the same manner. The supplemental disk 66' is carried by and associated with an angle frame-bar 67 in the same manner as the disk 5 is associated with its standard, the bend or angle 68 of the frame-bar 67 being bolted to the hitch-bar 23,

as clearly shown. The outer end of the supplemental hitch-bar 65 of course projects beyond the hitch-bar 23, and to this extended end the clevis 22 is pivoted, a rod 26 connecting the clevis with the ear 27, projectingT from the sleeve or casting 1S, as shown in Fig. l. Of course when the supplemental disk is employed it will be necessary to remove the front furrow-wheel out-ward to one side in order to permit proper draft upon the machine, and to accomplish this result the arm 210i? the said furrow-wheel is elongated and provided with an angular offset 69, which is bolted, respectively, to the angular' frame-bar (57 and to the bracket l2 of the land-side wheel.

The seat-standard is herein shown as provided with a seat 70, which is employed where the plow is to be used as a riding implement; but should it be desired to convert the same into a walking-plow handles 71 are to be attached to the seat-standard, as shown in dotted lines in Fig. l.

From the foregoing description it will be seen that every element and adjustment requisite to the presentation of a thoroughly effective disk plow is provided and that by reason of the simplicity of the construction of the parts should one or more become broken or deranged they may readily be replaced. Furthermore, by the employment of the rocking hitch-bar and its connection with the rear portion ofthe frame-beam the desired downward pressure may be readily and quickly imparted to the disk or disks by simply detaching the doubletree -hook from one opening in the clevis and moving it to another.

Vhile not herein shown, it is to be understood that a suitable scraper may be employed in connection with the disk or disks to keep the same free from any accumulation of soil.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

I. In a plow, a frame carrying a disk, and means coacting with the rear portion of the frame and operated by change in the line of Y draft to vary the cut of the disk.

2. In a plow, a frame carrying a disk, a clevis, and connections between the clevis and the rear portion of the frame, said connections operating upon chauge in line of the draft on the clevis to vary the force of contact between the disk and the ground.
